SPECIFICATION forming part of Letters Patent No. 604,526, dated May 24:,1898.

Application filed Time 26, 1897. Serial No. 642,489. (No model.)

To all whom it may concern:

Be it known that I, THOMAS JEFFERSON FOWLER, residing at Topaz, in thecounty of Mono and State of California, have invented a new and usefulPipe-Wrench, of which the following is a specification.

My invention relates to wrenches, and particularly to pipe-wrenches, andhas for its object to furnish a wrench of this class which shall beextremely simple in constructi on very strong, powerful inoperation,cheap, not liable to be broken in use, and composed of aminimum of parts.

With this object in view my invention consists in the improvedconstruction, arrangement, and combination of parts hereinafter fullydescribed, and afterward specifically pointed out in the appended claim.

In order to enable persons skilled in the art to which myinvention mostnearly appertains to make and use the same, I will now proceed todescribe its construction and operation in connection with theaccompanying drawings, in which- Figure 1 is a perspective view of apipewrench constructed in accordance with my invention in posit-ion upona section of pipe and ready for practical operation. Fig. 2 is a detailperspective view showing the several parts of which my improvedpipe-wrench is composed detached from each other.

Like letters of reference mark the same parts wherever they occur inboth figures of the drawings.

Referring to the drawings by letters, A is the handle of the Wrench,having through it two or more holes A and formed at its end with teeth Awhich cut into and grip the pipe being turned.

B is the movable jaw, provided at its front end with a curve B, theinside of which is V- shaped and provided with teeth 13 in both sides ofthe V, all pointed in the same direction, which will be opposite to theteeth A of the handle when the parts are connected together. The jaw 13is provided with two arms or cars B at its rear end and projecting fromthe bar on the same side as the curve B, set wide enough apart toembrace the handle, and having holes B as shown, the hole in one armbeing of less diameter than that of the other and screw-threaded. Thisjaw 13 has also two other arms B projecting from the same side thereofand about centrally between the curve B and arms 13 which arms 13 may besimilar in construction to the arms B but without perforations, and thesame distance apart.

0 is a connecting pivot-screw which is passed through one of the jaws Bthen through one of the perforations A in handle A, and finally threadedinto the opposite jaw B thus securely attaching the handle (or fixedjaw) A to the removable pivoted jaw 15, the arms B and B lying on bothsides of the handle A, acting as guides therefor and preventing wabblingor side strain or twist on the pivot O.

D is a section of pipe, such as gas or water pipe, and it is showngrasped between the jaws of the wrench in Fig. 1. An inspection of thisfigure in connection with Fig. 2 will show that the teeth A of thehandle-jaw engage the pipe on the opposite side from the teeth 13 of jaw13 and that they point in the same direction when considered inconnection with the periphery of the pipe D. \Vhen it is desired to turna pipe in either direction, the jaw B, swinging on pivot O, is placedover the pipe with the teeth in contact with the pipe and pointing inthe direction to be turned. By now pressing on the lever-handle, so asto bring its forward end toward jaw B, the teeth A will engage the pipe,as seen in Fig. 1, and pressure upon the lever will tightly grip thepipe between the jaws and carry it around in the direction the teeth arepointing. The more pressure there is required to start the pipe thetighter the jaws will grip it, and the pipe is bound to turn unless thehandle breaks. There can be no liability to slip, as the leverage issuch that the teeth will be forced into the metal of the pipe.

The wrench will operate upon a considerable range of sizes of pipewithout changing the pivot; but it can readily be changed to adapt thewrench to larger or smaller diameters of pipe.

My device is cheap, strong, powerful, and certain in operation, andwhile I have illustrated and described what I consider the best meansfor carrying out my invention 1 do not wish to be understood asconfining myself to the exact construction shown, but consider myselfentitled to all such slight changes or variations as might suggestthemselves to the ordinary mechanic, such changes and variations fallingclearly within the limit and scope of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent 0f the United States, is

In a pipe-Wrench, the combination of a handle-jaw having a series ofperforations and a curved or cam-shaped outer end provided with teeth, amovable jaw having its outer end curved or bent to one side, the insideof said jaw being V-shaped and provided with teeth on both sides of theV, two parallel arms proj ecting from the movable jaw on the same sideas its curved end, embracing the handle-jaw and having perforations toregister with those of the handle-jaw the perforations of one arm beingof less diameter than the other and screw-threaded,a pivot-screw passingthrough the perforation of one arm of the movable jaw and one of theperforations of the handle-jaw and threaded into the perforation of theother arm of the movable jaw, and a second pair of parallel guide-armsprojecting from the movable jaw on the same side as the curved end,between the curved end and the pivot-arms, all substantially as and forthe purpose set forth.
